Perhaps you should try some spelling variations:
"and optimization python python programming" » "and optimization method python programming" (Expand search), "and optimization option python programming" (Expand search), "and optimization methods python programming" (Expand search), "and optimization pythons python programming" (Expand search), "and optimization piton python programming" (Expand search), "and optimization pitons python programming" (Expand search)
"based convolution an coding program" » "based convolutional an coding program" (Expand search), "and convolution an coding program" (Expand search), "based evolution an coding program" (Expand search), "based convolution and coding program" (Expand search), "based convolution on coding program" (Expand search), "based convolutions and coding program" (Expand search), "based convolution an cloning program" (Expand search), "based convolution an loading program" (Expand search), "based convolution an cooling programs" (Expand search), "based convolution an encoding program" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("based convolution an coding program") OR ("and optimization python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based convolution an coding program\") OR (\"and optimization python python programming\"))".
• Removing quotes may allow a broader search: (( based convolution an coding program ) OR ( and optimization python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based convolution an coding program") OR ("and optimization python python programming"))*.
